A gyrus (plural gyri) is a bump or ridge on the surface of the brain.
The superior temporal gyrus is bounded by:
- the lateral sulcus above;
- the superior temporal sulcus (not always present or visible) below;
- an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly.
The superior temporal gyrus contains several important structures of the brain, including:
- Brodmann areas 41 and 42, marking the location of the primary auditory cortex, the cortical region responsible for the sensation of sound;
- Wernicke's area, Brodmann 22p, an important region for the processing of speech so that it can be understood as language.
